Description
Technical field
The present invention relates to a kind of belt fastener.
Background technology
At present, the belt fastener operation principle of auto lock on the market is：When adjusting belt tightness degree, thumb pins skin
Buckle, with forefinger rotating handles, revolving fragment (ratchet) is set to depart from ratchet, then belt freely can loosen or tighten up.When locking skin
During band, forefinger departs from handle, and revolving fragment is resetted under magnet effect, while revolving fragment is resisted against on ratchet.
The belt fastener of existing auto lock has the following disadvantages：First, adjustment elasticity is cumbersome, when belt is very tight
When, revolving fragment can cut fine with ratchet, and handle is difficult to rotate, it is necessary to can just be untied with very great strength.Second, structure is multiple
Miscellaneous and quality is heavier；Existing belt fastener part is more, is easily damaged, and part is more, and weight is bigger.
The content of the invention
The invention provides a kind of belt fastener, it is intended to which the belt fastener for solving existing auto lock easily causes skin because of locking
Buckle unties the problem of relatively elaborate.
In order to solve the above technical problems, the present invention is achieved through the following technical solutions：
A kind of belt fastener, including body, plate control body and for limit the ratchet with body position；The rear end of body is provided with band body
Clamping part, and the front end switching of body has the rotating shaft that left and right directions is set；Plate control body front end is provided with the band body that fore-and-aft direction is opened
Pair places hole, and plate control body is fixedly connected with rotating shaft；The outer surface of body front end is provided with groove, and ratchet is located in groove, ratchet
Front end is fixed in rotating shaft, and back-moving spring is provided between the rear end of ratchet and the rear end of bottom portion of groove；Body outer surface is provided with master
Position-limited rack, the band body master that fore-and-aft direction is opened is surrounded between main position-limited rack and body outer surface and places hole.
Further, clamping part is by the neck that is arranged on body rear end face and is matched with body phase and for will be fixed on body
Fixing screws in neck are formed.
Further, body is provided through the first through hole of groove, and the front end of ratchet is provided with the second through hole；Plate control body rear end is left
Right both sides are equipped with connecting hole；Rotating shaft is located in first through hole, the second through hole and connecting hole；Rotating shaft is articulated in first through hole
Interior, the second through hole and connecting hole are fixedly connected with rotating shaft.
Further, hole is placed with body pair to be surrounded with the secondary position-limited rack for being arranged on the internal surface of plate control by plate control body.
Further, plate control body is the U-frame frame of an open rearward end.
Further, the ratchet includes fixed part and kink, and fixed part is fixedly connected with rotating shaft, and kink is arranged on solid
Determine the rear end in portion and outward bending.The pawl structures are used for and the band body containing ratchet is used cooperatively.
Further, ratchet is triangle or square laminated structure.
Further, ratchet is the arc pressuring plate of evagination, and the outer surface of arc pressuring plate is provided with anti-slip veins.Anti-slip veins are set, with
Corresponding to the with body surface of belt can be smooth, by the anti-slip veins of ratchet and with the frictional force between body come fixing band
The position of body.The with body surface of certain corresponding belt can also set the measure of the increase friction such as anti-slip veins.
Compared with prior art it is an advantage of the invention that：
1st, by pressing lightly on plate control body and body junction in the present invention, band body can be departed from pawl, so as to
To adjust the elasticity of belt, even if the comparison that belt is received is tight, can also easily open.
2nd, present invention eliminates the panel above belt fastener, magnet etc.；Structure simplifies so that overall to become lighter.
3rd, in action of reset spring lower plate control body and ratchet pawl reset, ratchet is resisted against on band body, so as to limit with body
Position, realize the function of auto lock.
